Re: Texture Pack [128x] Sphax PureBDcraft [(REAL)Technic 6.0.7 / Tekkit 2.1]
Tekkit 2.1. I have found a fix on the eclipse site that you linked in OP and can send you completed pack for 2.1 if you would like.

Continuing the short trend of on topic posts:
I downloaded the pack and dropped it into technic and everything was great. Kudos to you good sir. Here's my problem, when I dropped the exact same pack into tekkit a few mods still run off of default textures (railcraft, and additional objects for example). I read the whole thread on my phone so I may have missed it, but has anyone found a solution or am I just doing it wrong? Also before anyone flames me for asking a tekkit question on the technic board, OP says the pack also works with tekkit so this seemed the best place for this question.
It just hit me that this may be due to tekkit and technic having slightly different versions of some mods. Will research and post back.

You are most likely using modifyworld.jar or some other protection plugin. All you have to do is give the fake user [redpower] build rights in the area and they will work. You should probably add [buildcraft] [forestry] as well

My server had this issue. Somehow the item id for enderchest got changed in the server config files. It is 178 in the client files but on my server it had been changed to 251 somehow. Have your server admin change the ID and all will be well. Enderchests should still contain their inventory as well.

Wooden BC pipes on condensers tends to corrupt chunks when the pipe tries to pull from the target slot (top left) of the condenser. Redpower pipes however do not seem to have this problem and will ignore the target slot. Hope this helps

I have found that the Redpower pipes do not cause this crash, let your players know that if they want to pipe something out of an energy condenser they should use redpower pipes rather than buildcraft pipes.

The only thing I've been able to come up with on my server is to put the spawn in an entirely different world, then deny everyone build rights in that world via modifyworld.jar. However that has a dependency on PEX so if you don't want to use that you're out of luck.
